(3)Developing bias voltage check
Note: Use a digital multi-meter with an internal resistance of 10M
Ω
or
more.
1) Set the digital multi-meter range to DC700V.
2) Put the test rod of the digital multi-meter on the developing bias
voltage output check pin.
3) Turn on the power, execute SIM25-1.

(4) Grid bias voltage check
Note: Use a digital multi-meter with an internal resistance of 10M
Ω
or
more.
1) Set the digital multi-meter range to DC700V.
2) Put the test rod of the digital multi-meter on the grid bias voltage
output check pin.
3) Turn on the power.
(The voltage is outputted in the grid bias High output mode during
warming up, and in the grid bias Low output mode when warming up
warming up, and in the grid bias Low output mode when warming up
is completed.)

(1) Image position adjustment
a. OC image lead edge position adjustment (SIM 50-1)
Note: In advance to this adjustment, the sub scanning magnification ratio
adjustment must be performed.
1) Set a scale on the OC table as shown below.
2) Make a copy.
3) Check the copy output. If necessary, perform the following
adjustment procedures.
4) Execute SIM 50-01.
Select a desired mode with the arrow keys, enter the adjustment

5) Set the OC lead edge position set value (RRC-A) to [1]
The OC image scanning start position is shifted inside the document
edge.
6) Set the main cassette lead edge void adjustment value (DEN-A)* to [1]
The lead edge void becomes the minimum.
